Juperos Carded Jur

You also gain +5 atk per Skel Worker Card, but that's more like a subtle bonus.
It doesn't really matter how you card it, even a double PPE katar works completely fine. It basically boils down to which cards are cheaper at the moment.
And obviously, if you want to hunt large/small formless monsters on sin(x), then you might want to stay with triple PPE for better damage.
